On Sunday, six trains (i.e. train 1, train 2 and so on) are standing on six different platforms respectively from left to right facing North. Next day, all the trains are there on the same six platforms in such a way that no train is on the same platform as on the Sunday. On Monday, following observation are made: (i) Train 2 was immediately to the left of Train 5. (ii) Train 4 has Train 6 to its immediate left and neither of them were at Train 3’s original place. (iii) Train 1 has Train 3 on its immediate right and Train 5 on its immediate left. If an even numbered train is at the East end on Monday, which train is fourth from the right end.
